First Beach Reopened After Fukushima Nuclear Accident


A beach in Iwaki, in the province of Fukushima, won permission today for the summer bathing, thus becomes the first beach that opens its doors after the nuclear accident in 2011.

In Nokoso Beach, 65 kilometers south of the battered nuclear plant, three local tour guides inaugurated the reopening of the beach, on a day which coincides with the celebration of the holiday in Japan.

During the inauguration of the first open beach in Fukushima, there were musical performances and volleyball matches in the sand.

According to the city of Iwaki, the concentration of radiation in sea water is less than 1 becquerel per liter, while radiation in the air do not pose a risk to health, which has allowed swimming.

“The water is still cold, but I think it will be a good season. Many people want to come,” said one of the natives, Yukiei Hakozaki, 22.

The accident at the Fukushima Daiichi Nuclear Power Station was the worst since that of Chernobyl. It severely affected agriculture, livestock and local fisheries, as well as having forced the evacuation of about 80,000 people in an exclusion zone of 20 kilometers around the nuclear plant.

The plant operator of Tokyo Electric Power ( TEPCO ) has reported several times about the leak of radioactive water into the sea. The latest was in April, when there was a confirmation of a leak of 12 tons of liquid contaminated with radioactive strontium.

Since the beginning of the nuclear crisis and after the earthquake and tsunami of March, the authorities conduct tests to analyze the impact of the accident on marine life. As it is estimated that between March 21 and April 30 of last year, the plant could shed some 15,000 sea terabecquereles cesium and radioactive iodine.



Government Imposes Tax on Electricity Generation Companies



The government is preparing a tax on electricity generation to be applied depending on the billing. It is expected to be approved this Friday as part of the energy reform to end the tariff deficit, Europa Press reported sources in the electricity sector.

The content of this new measure could be advanced on Wednesday in Congress by the Prime Minister, Mariano Rajoy, and approved by the Executive two days later, during the Council of Ministers on Friday.

A fee based on turnover fits with the announcement of the Minister of Industry, Energy and Tourism, José Manuel Soria. The Government’s intention to impose on the electricity generating a rate that is homogeneous and at the same time, non-discriminatory.

In addition, the Executive believes that the have a legal basis to impose the fee after that in a recent judgment the Supreme Court vouch for the changes in the remuneration conditions of photovoltaics as a function of changes in the economic environment and energy.

The ruling, which comes to meet a demand for photovoltaic Anpier association against the limitation of years of eligible approved by the former Minister of Industry Miguel Sebastián, supports the compensation changes as long as they ensure a reasonable return to the facility .

With the turnover rate, the government tries to avoid firing the tariff deficit, which in cumulative sum is 24,000 million euros. And, in case no action is taken, it could add another 4,500 million euros this year .

466 euros per megawatt hour

The greatest impact of this tax on solar technologies is because the final billing in terms of euros per megawatt hour is much higher than other sources of generation.

The lots are paid for up to 466 euros per megawatt hour (MWh), compared to about 50 euros per MWh of average pay of other conventional technologies. The sun generates 10% of extracoste consumers pay in electricity bills.

However, the rate also significantly affect traditional technologies, producing a high volume of electricity. Its producers claim that these technologies such as nuclear, hydro or thermal, are capable of scoring in the wholesale markets pay a 10% lower than the European average.

Japan Recovers Nuclear Energy and May Lower Power Consumption


Japan recovered their supply of nuclear energy after the Oi reactor core (west), the first to be reactivated after the accident in Fukushima, began to generate and transmit electricity.

Unit 3 Oi plant in the western province of Fukui, was launched last Sunday, but the turbine was not connected to this day, which began generating and transmitting power to the grid.

The reactor is expected to increase its power gradually in the coming days and operate at full capacity on Monday, according to Kyodo.

The reactor, with an output of 1.18 million kilowatts, will help alleviate power shortages this summer in the west between 9 and 15%, so that the government, which had called for consumers to save 15% of energy these months could review the request.

In a statement, the president of KEPCO Electric, which owns the plant, said that the recovery is a “step forward towards providing stability and security” and stressed that this is the first time in four and a half months that the company provides electricity generated by atomic fission.

The Oi, thus became the first run back after the disaster that unleashed in the Fukushima Daiichi plant by the devastating earthquake and tsunami of March 2011.

That event put into question the safety of atomic units in Japan, a country that has 50 commercial reactors and previously obtained 30 percent of its electricity by nuclear means.

It is expected that following the approval of the government in mid-June, KEPCO will revive another of its Oi units in middle of this month, in order to be fully operational by the end of July.

Paris Confirms Reducing Portion of Nuclear Power to 50% in 2025


The French government confirmed that the share of nuclear energy in electricity production will be reduced from 75% today to 50% by 2025 and develop a “green economy”.

Thus, declared the French Prime Minister Jean-Marc Ayrault, who told the National Assembly, that his government will launch a “massive program of energy saving and an ambitious plan for renewable energy development”.

“The gas and electricity, like water, are common property and can not be left to the law of the market,” he premier said, adding, “We will launch a gradual charging, with a double objective, social and ecological”.

Ayrault confirmed the objectives set out during his presidential campaign by the head of state, the socialist Francois Hollande, who took office after the elections of last May 6th.

The Prime Minister said in his program of government intentions, which explained to the members before submitting to a vote of confidence, that the “ecological and energy transition” that intends to apply will be “creating new jobs”.

Ayrault advocated protecting the planet and to contribute to this, said that the government intends to lay the foundations for a “green economy”. He also said it will be based on “technological innovation”, which he said will be one of the elements of the country’s economic recovery.

The Uses of Solar Energy

The sun is our nearest star, and (directly or indirectly) the source of almost all the energy available on earth. The sun’s energy comes from nuclear reactions in the center of the sun where the temperature is 15 million° C. This is the Fusion, which combine the hydrogen atoms themselves. This creates a large amount of helium and energy is released.

Every second, there is about 600 million transfer of hydrogen into helium. This energy spreads in the form of light and heat into space. Nuclear fusion takes place in the sun for 5 billion years (the age of the sun) and this will continue for so long. Solar energy is the starting point of most energy sources.

The main principles of the direct utilization of solar energy are:

Solar collectors – the preparation of hot water and heating the rooms
Photovoltaics – the direct conversion of solar energy into electrical energy
The concentration (focusing) of solar energy – the energy consumption in large plants
